Description

Technical Field

[0001] This application relates to the field of spark detection and extinguishing technology, and in particular to a spark detection and extinguishing system and its detection device. Background Technology

[0002] In industrial production, dust explosions caused by sparks are a significant cause of accidents. During transport, flammable and explosive substances such as dust often generate tiny sparks due to electrostatic friction. When these sparks reach the dust removal chamber, the pressure rises back to near atmospheric pressure, causing the dust to reignite and potentially trigger an explosion.

[0003] Currently, spark detection and fire suppression systems are widely used in various industries (such as tobacco, textiles, papermaking, and wood processing). These systems can monitor spark generation in pipelines in real time and automatically perform fire suppression operations. However, in actual operation, the accuracy of spark detection and the system response time are affected by various factors, requiring regular testing of the system.

[0004] However, existing testing methods cannot accurately assess the system's operational reliability. Utility Model Content

[0015] Secondly, a spark detection and extinguishing system is provided, including a dust removal pipeline, a water supply pipeline, a spark detector, and the detection device as described above;

[0016] The spark simulation mechanism is used to generate laser signals in the dust removal pipeline to simulate sparks. The spark detector is used to detect the sparks generated in the dust removal pipeline and the sparks simulated by the spark simulation mechanism. The water supply control mechanism is used to control the water supply pipeline to switch water supply modes so as to supply water to the dust removal pipeline or the external recovery pipeline through the water supply pipeline. The flow detection mechanism is used to detect the flow rate of water in the water supply pipeline.

[0017] In one embodiment, the dust removal pipeline includes a main pipeline and at least one branch pipeline connected to the main pipeline; the spark simulation mechanism is disposed on the main pipeline, and the spark detector is disposed on the main pipeline at a position corresponding to the spark simulation mechanism; the end of the branch pipeline away from the main pipeline is disposed corresponding to the dust generating equipment.

[0018] In one embodiment, a mounting hole is provided on the main pipe at a position corresponding to the spark simulation mechanism. The mounting hole penetrates the pipe wall of the main pipe, and the spark simulation mechanism is sealed and embedded in the mounting hole by a sealing ring.

Detailed Implementation

[0029] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0032] Spatial relation terms such as “below,” “under,” “below,” “under,” “above,” “above,” etc., are used herein to describe the relationship between one element or feature shown in the figure and other elements or features.

For example, if the device in the figure is flipped, the element or feature described as “below,” “under,” or “below” will be oriented “above” the other element or feature. Therefore, the exemplary terms “below” and “under” can include both above and below orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0033] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. Furthermore, in the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if there is transmission of electrical signals or data between the connected objects.

[0034] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0035] As described in the background art, when the detection device in the prior art's spark detection and extinguishing system detects the spark detection and extinguishing system, there is a problem that the working reliability of the system cannot be accurately evaluated. After research by the inventor, it is found that the reason for this problem is that the existing detection usually simply tests whether the spark detector can be normally started manually, and cannot test the photosensitive intensity of the spark detector, resulting in a low detection accuracy of the spark detection and extinguishing system. At the same time, the existing detection device cannot display the actual states of the spark detector, each pipeline, the solenoid valve, and the water supply system during operation, and cannot comprehensively evaluate the linkage effect of each part during operation, making it difficult to accurately detect the stability effect and actual response speed of the spark detection and extinguishing system.

[0036] For the above reasons, the present invention provides a spark detection and extinguishing system and its detection device. By setting a detection device on the spark detection and extinguishing system, the water supply control mechanism can cut off the passage between the water supply pipeline and the dust removal pipeline during the detection process to ensure that the test water flow of the water supply system does not enter the dust removal pipeline during the test. The spark simulation mechanism can simulate the generation of sparks in the spark detection and extinguishing system through the spark simulation mechanism, so that the spark detector can detect the simulated sparks in a real environment, which is closer to the actual working environment. At the same time, the main control mechanism can control the intensity of the simulated sparks generated by the spark simulation mechanism to test the photosensitive intensity of the spark detector to ensure the accuracy and reliability of the detection. In addition, the main control mechanism can also collect the flow signals of the flow detection mechanism to detect the linkage effect between the spark detector, each pipeline, the solenoid valve, and the water supply system.

[0037] In one embodiment, as Figure 1 and Figure 5 shown, a detection device for a spark detection and extinguishing system is provided. The detection device includes a main control mechanism 100, a spark simulation mechanism 200, a water supply control mechanism 300, and a flow detection mechanism 400. The spark simulation mechanism 200 is installed on the dust removal pipeline of the spark detection and extinguishing system and is correspondingly arranged with the spark detector 800 of the spark detection and extinguishing system. The spark simulation signal input end of the spark simulation mechanism 200 is electrically connected to the spark simulation signal output end of the main control mechanism 100; the water supply control mechanism 300 is connected to the water supply pipeline of the spark detection and extinguishing system, and the opening and closing control signal input end of the water supply control mechanism 300 is electrically connected to the opening and closing control signal output end of the main control mechanism 100; the flow detection mechanism 400 is arranged on the water supply pipeline of the spark detection and extinguishing system, the water supply pipeline is connected to the dust removal pipeline, and the flow detection signal output end of the flow detection mechanism 400 is electrically connected to the flow detection signal input end of the main control mechanism 100.

[0038] The spark simulation mechanism 200 can be used to simulate the generation of sparks in the dust removal pipeline. For example, the spark simulation mechanism 200 can simulate a spark by generating light, allowing the spark detector 800 in the spark detection and extinguishing system to detect the sensitivity and accuracy of its detection of real sparks by measuring the sensitivity of the light. This determines whether the system can trigger subsequent extinguishing actions in a timely and accurate manner during operation, thereby evaluating whether the performance of the entire spark detection and extinguishing system meets the standards. Optionally, the light intensity generated by the spark simulation mechanism 200 is adjustable, which allows for testing of the light sensitivity of the spark detector 800, thereby accurately evaluating the detection performance of the spark detector 800 under different light intensity conditions (i.e., different spark sizes).

[0039] The water supply control mechanism 300 can be used to control the water supply mode of the water supply pipeline. In specific implementation, depending on the working status of the entire spark detection and extinguishing system, the water supply pipeline can include a first water supply mode when the spark detection and extinguishing system is operating normally and a second water supply mode when the spark detection and extinguishing system is being tested. When the water supply pipeline operates in the first water supply mode, the spark detection and extinguishing system operates normally. At this time, the water supply system is connected to the dust removal pipeline through the water supply pipeline so that when the spark detector 800 detects a real spark in the dust removal pipeline, water is supplied to the dust removal pipeline through the water supply system for fire extinguishing. When the water supply pipeline operates in the second water supply mode, the spark detection and extinguishing system is tested. At this time, the water supply system is connected to the external recovery pipeline through the water supply pipeline so that when the spark detector 800 detects light (i.e., simulated spark) generated by the spark simulation mechanism 200 in the dust removal pipeline, water is diverted through the water supply pipeline to the recovery pipeline and discharged to prevent test water from entering the dust removal pipeline, thereby avoiding interference with the normal working environment of the dust removal pipeline and reducing unnecessary wear and tear on the equipment inside the dust removal pipeline.

[0040] In an optional embodiment, the water supply control mechanism 300 may include a control relay (not shown) and a switching transistor (not shown). In specific implementation, the control relay and the switching transistor can be implemented using existing structures. For example, during wiring, one end of the relay coil of the control relay can be connected to a first power supply voltage, and the other end of the relay coil can be electrically connected to the collector of the switching transistor. The base of the switching transistor forms the opening and closing control signal input terminal of the water supply control mechanism 300 and is electrically connected to the main control mechanism 100. The emitter of the switching transistor is grounded. The normally open contact of the control relay is connected to the three-way solenoid valve 900 in the spark detection and extinguishing system to control the opening degree of the three-way solenoid valve 900, thereby realizing the switching of the water supply mode of the water supply pipeline. The common terminal of the control relay is connected to a third power supply voltage.

[0041] The flow detection mechanism 400 can be used to monitor the flow rate of water in the water supply pipeline in real time, so that the main control mechanism 100 can determine whether the water supply volume of the water supply system matches the light intensity generated by the spark simulation mechanism 200 based on the flow rate and the light intensity generated. On the one hand, by determining whether the water supply system is discharging water, the timeliness of the response of the water supply system when sparks are generated in the dust removal pipeline can be detected. On the other hand, by determining the flow rate of water in the water supply pipeline, the operating effect of the water supply system when sparks are generated in the dust removal pipeline can be detected, that is, whether the water output matches the spark size can be detected to ensure that the spark can be extinguished in a timely and rapid manner.

[0042] For example, when testing the spark detection and extinguishing system, the water supply control mechanism 300 can switch the water supply pipeline to a second water supply mode under the control of the main control mechanism 100. For instance, the main control mechanism 100 can generate a corresponding opening / closing control signal via an external test command and output it through the opening / closing control signal output terminal. The water supply mechanism can receive the opening / closing control signal through the opening / closing control signal input terminal and control the three-way solenoid valve 900 in the water supply pipeline to switch to the second water supply mode, preventing water from entering the dust removal pipeline during the test. Subsequently, the spark simulation mechanism 200 can generate light of different intensities to simulate sparks of different sizes under the control of the main control mechanism 100. For instance, the main control mechanism 100 can generate corresponding PWM (Pulse Width Modulation) signals, current signals, etc., via an external test command and output them through the spark simulation signal output terminal. The spark simulation mechanism 200 can receive the current signal through the spark simulation signal input terminal and generate light of different intensities in the dust removal pipeline to simulate sparks of different sizes. At this time, the spark detector 800 can detect the light generated by the spark simulation mechanism 200. When the spark detector 800 detects the light, it can convert the detected light signal into an electrical signal and transmit it to the main control mechanism 100. This allows the main control mechanism 100 to control the water supply system to start and supply water to the water supply pipeline based on the electrical signal. The flow detection mechanism 400 can detect the water flow in the water supply pipeline in real time and convert the flow into a flow signal (such as a digital signal) that the main control mechanism 100 can recognize. The flow signal is then output through the flow detection output terminal. The main control mechanism 100 can receive the flow signal through the flow detection input terminal, and compare the flow signal with the output current signal after normalization to determine whether the flow signal matches the current signal (i.e., the size of the simulated spark), thereby realizing the testing of the spark detection and extinguishing system.

[0043] In an exemplary embodiment, the main control unit 100 can be implemented using one or more of the following: a microcontroller unit (MCU), a general-purpose processor, an application-specific integrated circuit (ASIC), a digital signal processor (DSP), a digital signal processing device (DSPD), a programmable logic device (PLD), a microprocessor, a programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, or a quantum computing-based data processing logic unit. Specifically, the main control unit is implemented using a microcontroller unit, for example, an STM32F103C8T6 microcontroller. This allows it to respond to external test commands by sending current signals to the spark simulation mechanism 200, opening and closing control signals to the water supply control mechanism 300, sending water supply signals to the water supply system, and receiving electrical signals from the spark detector 800 and flow signals from the flow detection mechanism 400. It also converts and matches the flow signals with the current signals to achieve testing of the spark detection and extinguishing system. It is understandable that although the main control unit 100 can generate, transmit and process signals, this embodiment mainly provides a circuit architecture that can achieve the aforementioned functions. The main control unit can be implemented using existing chips or power supply modules, and does not involve any improvement to the specific control program.

[0044] The detection device of the aforementioned spark detection and extinguishing system comprises a main control mechanism 100, a spark simulation mechanism 200, a water supply control mechanism 300, and a flow detection mechanism 400. The spark simulation mechanism 200 is installed on the dust removal pipeline of the spark detection and extinguishing system and corresponds to the spark detector 800 of the system. The spark simulation signal input terminal of the spark simulation mechanism 200 is electrically connected to the spark simulation signal output terminal of the main control mechanism 100. The water supply control mechanism 300 is connected to the water supply pipeline of the spark detection and extinguishing system, and its opening / closing control signal input terminal is electrically connected to the opening / closing control signal output terminal of the main control mechanism 100. The flow detection mechanism 400 is installed on the water supply pipeline of the spark detection and extinguishing system, and the water supply pipeline is connected to the dust removal pipeline. The flow detection signal output terminal of the flow detection mechanism 400 is electrically connected to the flow detection signal input terminal of the main control mechanism 100. Integrated into the spark detection and extinguishing system, this detection device allows for testing based on the actual working scenario of the dust removal pipeline before system operation. During testing, the main control mechanism 100 controls the spark simulation mechanism 200 to generate simulated sparks of varying intensities, enabling testing of the detection accuracy of the spark detector 800. Furthermore, the water supply control mechanism 300 can divert water from the water supply system to the recovery pipeline during testing to prevent test water from flowing into the dust removal pipeline. Simultaneously, the flow detection mechanism 400 can provide real-time feedback on the water flow rate to test the matching degree between the water supply flow rate and the spark size, thereby improving the realism and accuracy of the test.

[0045] In one embodiment, such as Figure 2 As shown, the spark simulation mechanism 200 includes a light generation module 210 and a light driving module 220. The input terminal of the light driving module 220 forms a spark simulation signal input terminal and is electrically connected to the main control mechanism 100. The light control output terminal of the light driving module 220 is electrically connected to the light control input terminal of the light generation module 210. The light generation module 210 is installed on the dust removal pipeline.

[0046] The light generating module 210 can be used to generate light of different intensities in the dust removal pipeline. In some embodiments, the light generating module 210 can be implemented using light-emitting diodes, lasers, etc., to generate light of different intensities in the dust removal pipeline. The light driving module 220 can be used to drive the light generating module 210 to emit light, so as to ensure that the current signal generated by the main control mechanism 100 can accurately control the light emission intensity of the light generating module 210, thereby achieving precise adjustment of the light intensity to simulate sparks of various sizes.

[0047] For example, when the main control mechanism 100 generates a current signal, it can be input to the light driving module 220 through the input terminal of the light driving module 220, so that the light driving module 220 receives the current signal. Then, the light driving module 220 can drive the light generating module 210 to generate light of corresponding intensity according to the current signal, so as to simulate the generation of sparks in the dust removal pipeline.

[0048] In one embodiment, the light generating module 210 includes a laser diode 211, the negative terminal of which forms the light control input terminal of the light generating module 210 and is electrically connected to the light driving module 220, and the positive terminal of the laser diode 211 is connected to a first power supply voltage.

[0049] The positive terminal of the laser diode 211 is connected to the first power supply voltage, and the negative terminal is connected to the light drive module 220. When the light drive module 220 outputs a drive signal that meets the conduction conditions of the laser diode 211, the laser diode 211 conducts and emits light to simulate the generation of a spark. Furthermore, the brightness of the laser diode 211 can be adjusted by the magnitude of the connected drive current to simulate sparks of different sizes. Conversely, when the light drive module 220 stops outputting the drive signal, the laser diode 211 is turned off and extinguished to stop simulating a spark and end the test.

[0050] In some other embodiments, the light generating module 210 can also be implemented using light-emitting diodes. To further enhance the realism of the simulation, a red light-emitting diode can be selected to simulate the generation of sparks.

[0051] In an exemplary embodiment, taking the light generating module 210 as a laser diode 211 and the light driving module 220 as a transistor as an example, the transistor can be an NPN transistor or a PNP transistor. For example, NPN transistors such as S9013, S9014, S9018, and 2N2222 can be used, as well as PNP transistors such as 2SA812, 2SA1013, 2SA1015, and 2SA1037 can be used. The laser diode 211 can be implemented using an infrared light-emitting diode. In specific implementation, the base of the transistor forms a spark analog signal input terminal, which is electrically connected to the spark analog signal output terminal of the main control mechanism 100 through a first resistor to receive the current signal generated by the main control mechanism 100. The emitter of the transistor is grounded, and the collector of the transistor forms the light control output terminal of the light driving module 220, which is electrically connected to the light control input terminal formed by the negative terminal of the laser diode 211 through a second resistor. The positive terminal of the laser diode 211 is connected to a first power supply voltage. Based on the driving voltage of the laser diode 211, the first power supply voltage can be 3.3V.

[0052] For example, when the main control mechanism 100 generates a current signal, it can input the transistor through the base of the transistor, causing the transistor to enter the corresponding operating state of conduction or cutoff. When the transistor is on, it can provide a conduction path for the laser diode 211 to drive the laser diode 211 to emit light; conversely, when the transistor is off, it can cut off the conduction path for the laser diode 211 to control the laser diode 211 to turn off.

[0053] In one embodiment, the flow detection mechanism 400 includes a flow meter 410. The output terminal of the flow meter 410 forms the flow detection signal output terminal of the flow detection mechanism 400 and is electrically connected to the main control mechanism 100. The power supply terminal of the flow meter 410 is connected to a second power supply voltage.

[0054] For example, the flow meter 410 can monitor the flow rate of water in the water supply pipeline in real time, and convert the monitored flow rate into a digital flow signal through an analog-to-digital converter chip or module and transmit it to the main control unit 100. This allows the main control unit 100 to determine whether the timeliness and accuracy of the spark detection and extinguishing system's response to the spark meet the standards based on the flow signal and the output current signal.

[0055] In practice, the flow meter 410 can be implemented using a Hall effect flow meter 410. For example, it can be implemented using Hall effect flow meters 410 with models such as HF10PP05, USN-HS20TA, SEN-HZ06K, YF-S401, etc. For the specific wiring of each flow meter 410, please refer to the technical manual, which will not be elaborated here.

[0056] In one embodiment, such as Figure 4 As shown, the detection device of the spark detection and extinguishing system also includes a power supply module 500. The power supply module 500 has a first voltage output terminal for outputting a first power supply voltage and a second voltage output terminal for outputting a second power supply voltage. The first voltage output terminal is electrically connected to the main control mechanism 100 and the spark simulation mechanism 200, and the second voltage output terminal is electrically connected to the water supply control mechanism 300 and the flow detection mechanism 400.

[0057] The power module 500 supplies power to the main control mechanism 100, the spark simulation mechanism 200, the water supply control mechanism 300, and the flow detection mechanism 400. The first power supply voltage can be 3.3V, and the second power supply voltage can be 5V. The power module 500 is connected to an external power source, which can be 12V, such as a battery or dry cell battery. The power module 500 can regulate and step down the external power supply, outputting a first power supply voltage through a first voltage output terminal and a second power supply voltage through a second voltage output terminal to power different mechanisms. For example, the first power supply voltage can be provided to the laser diode 211 of the main control mechanism 100 and the spark simulation mechanism 200 to ensure their normal operation, and the second power supply voltage can be provided to the flow meter 410 of the water supply control mechanism 300 and the flow detection mechanism 400 to ensure their normal operation.

[0058] In an optional embodiment, the power module 500 may further have a third voltage output terminal that outputs a third power supply voltage. This third voltage output terminal is electrically connected to the three-way solenoid valve 900 in the spark detection and extinguishing system to provide power for the operation of the three-way solenoid valve 900. Specifically, the third power supply voltage may be 12V.

[0059] In practice, the power module 500 can be implemented using a power management chip. For example, the power module 500 can use a power management chip such as LM2596, TPS5430, or AXP313A. Its peripheral circuits and specific wiring methods can be implemented through the technical manuals of each chip and existing methods, which will not be elaborated here.

[0060] In one embodiment, such as Figure 4 As shown, the detection device of the spark detection and extinguishing system also includes a display mechanism 600, the display signal input terminal of the display mechanism 600 being electrically connected to the display signal output terminal of the main control mechanism 100.

[0061] The display mechanism 600 is used to display the light intensity generated by the spark simulation mechanism 200, the water supply mode of the water supply control mechanism 300, the real-time flow detected by the flow detection mechanism 400, and the water supply volume of the water supply system, so that operators can intuitively understand the detection parameters of the spark detection and extinguishing system.

[0062] For example, the main control unit 100 can transmit the light intensity generated by the spark simulation unit 200, the water supply mode of the water supply control unit 300, the real-time flow detected by the flow detection unit 400, and the water supply volume of the water supply system to the display unit 600, and the display unit 600 can display the information transmitted by the main control unit 100.

[0063] In practice, the display mechanism 600 can be implemented using LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), LED (Light Emitting Diode) dot matrix screen, digital tube, etc. For example, the display mechanism 600 can be implemented using an LCD display screen with model number JLX12864G-086-PC.

[0064] In one embodiment, such as Figure 5 As shown, a spark detection and extinguishing system is provided, including a dust removal pipeline, a water supply pipeline, a spark detector 800, and a detection device; the detection device can be implemented using the detection devices in the above embodiments.

[0065] Furthermore, the spark simulation mechanism 200 is used to generate laser signals in the dust removal pipeline to simulate sparks, the spark detector 800 is used to detect the sparks generated in the dust removal pipeline and the sparks simulated by the spark simulation mechanism 200, the water supply control mechanism 300 is used to control the water supply pipeline to switch the water supply mode so as to supply water to the dust removal pipeline or the external recovery pipeline through the water supply pipeline, and the flow detection mechanism 400 is used to detect the flow rate of water in the water supply pipeline.

[0066] One end of the dust removal pipeline is connected to the dust generating equipment 10 (e.g., machining equipment), and the other end is connected to the dust removal equipment 20.

[0067] When the spark detection and extinguishing system is operating normally, the main control unit 100 can control the water supply control unit 300 to switch the water supply pipeline to the first water supply mode. Dust generated by the dust generating equipment 10 can enter the dust removal equipment 20 for dust removal along the dust removal pipeline. When the dust moves along the dust removal pipeline and passes the spark detector 800, if the spark detector 800 detects a spark generated by the dust, the spark detector 800 can transmit the detection signal to the main control unit 100, so that the main control unit 100 can control the solenoid valve between the water supply system and the water supply pipeline to open, so that the water in the water supply pipeline can enter the dust removal pipeline to extinguish the spark. If the spark detector 800 does not detect a spark, the dust can directly enter the dust removal equipment 20 for dust removal.

[0068] When the spark detection and extinguishing system is running for testing, the dust generating device 10 and the dust removal device 20 are not working. The main control mechanism 100 can control the water supply control mechanism 300 to switch the water supply pipeline to the second water supply mode. Then, the main control mechanism 100 can control the spark simulation mechanism 200 to generate light of corresponding intensity to simulate a spark. If the spark detector 800 is normal, the spark detector 800 can detect the light generated by the spark simulation mechanism 200 (i.e., simulated spark) and transmit the detection signal to the main control mechanism 100. This allows the main control mechanism 100 to control the solenoid valve between the water supply system and the water supply pipeline to open, so that the water in the water supply pipeline can enter the recovery pipeline for discharge. During the discharge process, the flow detection mechanism 400 can detect the flow rate of the water in real time and transmit the flow signal to the main control mechanism 100. This allows the main control mechanism 100 to determine whether the spark detector 800, the water supply system, etc. are working properly, so as to realize the testing of the spark detection and extinguishing system.

[0069] The spark detection and extinguishing system in this embodiment, through the integration of a detection device, can perform detection before the spark detection and extinguishing system is put into operation, ensuring that each component in the spark detection and extinguishing system can work normally and stably, thereby improving the safety of production and processing.

[0070] In one embodiment, the dust removal pipeline includes a main pipeline 710 and at least one branch pipeline 720 connected to the main pipeline 710; a spark simulation mechanism 200 is disposed on the main pipeline 710, and a spark detector 800 is disposed on the main pipeline 710 and at a position corresponding to the spark simulation mechanism 200; one end of the branch pipeline 720 away from the main pipeline 710 is disposed corresponding to the dust generating device 10.

[0071] In this configuration, branch pipes 720 are correspondingly arranged to dust-generating devices 10. This can be a one-to-one correspondence between branch pipes 720 and dust-generating devices 10, or a one-to-many or many-to-one arrangement, ensuring that dust generated by each dust-generating device 10 can enter the main pipe 710 through its corresponding branch pipe 720. Optionally, a funnel-shaped dust inlet can be provided at the end of the branch pipe 720 furthest from the main pipe 710 to improve dust removal efficiency. Specifically, a negative pressure device can be used to create negative pressure within the main pipe 710 and branch pipes 720, allowing dust to be drawn into the branch pipe 720 through the dust inlet and then move along the main pipe 710 to the dust removal device 20 for dust removal. In other embodiments, a suction head can be provided at the dust inlet location to further enhance the dust removal effect.

[0072] Both the spark simulation mechanism 200 and the spark detector 800 are installed on the main pipe 710. Optionally, the spark simulation mechanism 200 can be set within the detection range of the spark detector 800, so that when testing the spark detection and extinguishing system, the spark detector 800 can accurately detect the light generated by the spark simulation mechanism 200, thereby improving the accuracy of the test.

[0073] In an optional embodiment, a mounting hole (not shown) is provided on the main pipe 710 at a position corresponding to the spark simulation mechanism 200. The mounting hole penetrates the pipe wall of the main pipe 710, and the spark simulation mechanism 200 is sealed and embedded in the mounting hole by a sealing ring (not shown).

[0074] In practice, the laser diode 211 can be embedded in the mounting hole through a sealing ring, allowing the light from the laser diode 211 to be transmitted into the main pipe 710 and detected by the spark detector 800. Optionally, the laser diode 211 can also be partially installed in the mounting hole, as long as the light from the laser diode 211 can be smoothly transmitted into the main pipe 710. This arrangement can also prevent the laser diode 211 from penetrating deep into the main pipe 710 and affecting the dust removal process, and at the same time, it can also prevent sparks generated in the main pipe 710 from damaging the laser diode 211.

[0075] In one embodiment, the water supply pipeline includes a water supply pipe 730, an inlet pipe 740, and a drain pipe 750. The water supply pipe 730, inlet pipe 740, and drain pipe 750 are connected by a three-way solenoid valve 900. The three-way solenoid valve 900 is electrically connected to a water supply control mechanism 300. The end of the water supply pipe 730 away from the three-way solenoid valve 900 is connected to a water supply system. The end of the inlet pipe 740 away from the three-way solenoid valve 900 is connected to a main pipe 710. The end of the drain pipe 750 away from the three-way solenoid valve 900 is connected to a main pipe 710. One end of the solenoid valve 900 is connected to the recovery pipeline; the water supply control mechanism 300 is also used to control the three-way solenoid valve 900 to connect the water supply pipeline 730 and the inlet pipeline 740 when the water supply pipeline is working in the first water supply mode, so that the water supply system supplies water to the main pipeline 710; the water supply control mechanism 300 is also used to control the three-way solenoid valve 900 to connect the water supply pipeline 730 and the drain pipeline 750 when the water supply pipeline is working in the second water supply mode, so that the water supply system drains water to the recovery pipeline.

[0076] The three-way solenoid valve 900 can selectively connect the water supply pipe 730 to either the inlet pipe 740 or the drain pipe 750 to control the switching of the water supply pipeline between the first and second water supply modes. When the water supply pipeline operates in the first water supply mode, the water supply pipe 730 is connected to the inlet pipe 740. When the spark detector 800 detects a spark generated by dust, water in the water supply system can sequentially flow through the water supply pipe 730 and the inlet pipe 740 into the main pipe 710 to extinguish the spark. When the water supply pipeline operates in the second water supply mode, the water supply pipe 730 is connected to the drain pipe 750. When the spark detector 800 detects light emitted by the laser diode 211, water in the water supply system can sequentially flow through the water supply pipe 730 and the drain pipe 750 into the recovery pipeline and be discharged. This allows the spark detection and extinguishing system to switch between different operating modes, improving the reliability and safety of the spark detection and extinguishing system.
